To all" f1.0 7mm? f'z may, concert/u:

Be it knowny that LJULIA'N S'rnZYo/Ziiow'- siii, a citizen of the United States, residing at New' Yorlc, county'` ot New York, and State ot NewSYork, have inventedicertain newf and useful Improvements iny Antoniow bile .Tirlesoic which? the following is a specification.

TheI principal object o-"thisi invention is to provide a. new and .improved `construction ina protective tread adapted to Vbe used' as a part' ot the outer shoe` of anV inflat-able automobile tire. l

A further. objectais toprovide a laminated structure consisting of: a plurality otsheets oi" suitablematerialihaying af metallic mesh reinforcementarranged between andpressed intol the V adjacent` sheets.

Ainothervobject isi-to provide a. simple and inexpensive construction ot a protective treadl which williv effectively safeguard the tire tioinbeingpnnctuned, will haye a high trictional coetcientfto enable the protective tread toexertasufficient' tractive effect, and which will have suiiicientresiliency'. to. maintain the' easy riding qualities of the inflatablev tire whileI at the/same' time Vpossessing sulticient resist-ance to wearto insure longevity oi!` service.

For the accomplishment offtlhese and-such further objectsas will hereinatterfbe apparent to those skilled'l intheart towhich this appertains the inventionv consistsin the constmction,v combination and 'arrangement-ot parts herein lspecifically described andi illuscrafted inv the accompanyingdra-wings, wherein is shownfa prefer-red embodiment ot the inventit-m, but it is tof be understood that changes, variations and modifications may be resorted-'to which fia-ll within the scope of the claims hereunto appended.r

In the drawings forming a portionv of this-specification l Fig. 1 isa side elevation partly in section ot a portion' of an inflatable tire'- embodying a protective tread' in' accordancewith my invention. 5

is shown in: Figs. 1 to 5 oi thedrawings the'nunieral 1() indicates the Wheel rimr having its-v side edges curved up to form a' retaining means for the clincher bead of the tirez y Aas-showny in Fig. 2V the outer shoe-ot my improved tire preferably consists ofl av plurality oli sheets 11 o1 any. suitable fab 1ic such. as canvas which are wrapped about a rubber bead 12, having a reinforcing- Wire i3,therein. Theit'abric sheets 11 aref eX- tended to: 'torni the side portions 1:4 of the tirel and the free ends otsaid sheets are extended' substantially.normal to theI outer circumference ot' the tire asfat 15. A plurality of annular' sheets .16 are constructed ci" rubber, libre7 wood, leather, paper, pressedpulp, canvas or any other suitable material'having highv rictionalf coeilicient to.I insure a suitable tractive eect and. Otten ingsuihcient resistance to wearY while possessing su-ficient degree or" vresiliency' to'in,v sure al noiseless tread and maintain the easy riding qualities of the intlatabletire; The ends 15 ot the fabric sheets 12 are placed between the annular sheetsfl and. a metallicopen meshcd wire structure 17' is interposed between each end?. and its adjacent annular sheet 161,. the sheets 16',.ends,15. and wirel structure 17: beingv firmlyv pressed to'- gethcr to cause thc strands-ofthe wireystruc'- ture to be imbedded into the fabricand annular sheetssof. as to bind: them into a unitary central treadstructurea. AS1 shown in the.'drawingl the central tread; structure con.- sists ot eight' ,ends'15,.the. two central ones 'beingf'in' juxtaposition and having al wire structure 17. therebetween, and. six. sheets 16 alternating with the remaining siXends- 15 and: there` being a: wire structure 1T between each' of the remainingsie;y sheets and ends. Obviously the number ot ends. 15, wire structures 17. andannular sheets 16 use-'df for the central tread unit and: the relative arrangement-thereof may be varied' as desired.

A air. of side tread units are eaclr composed eta plurality of' annular sheetsv 16 similar to those used for the central tread unit and having a metallic structure 17 interposed therebetween. The outer annular sheets 16 of the side tread units are of different' heights as shown to provide in effect inclined outer sides on thetread against which the rings 18, 19 of sheet steel or other suitable metal are clamped. Ring 18 is provided on its inner surface with a plurality of threaded bosses 2O in which the threaded ends of screws 21 engage, while the other ring 19 is provided on its outer face with the bosses 22 which are apertured and countersunlr to receive the fiat heads 23 of said screws. The usual inflatable inner tube 25 is contained within the tire as shown.

In the modification shown in Fig. 6 I have shown a tread constructed as heretofore described of annular sheets 16 and metallic wire structure 17 and designed to be used as an attachment to the common and well known types of outer shoes, a pair of sheet metal rings 18, 19 and screws 2l being provided to hold the laminated tread structure together and to the tire. In this form of the invention the laminat-ed tread structure is preferably constructed of a pair of similar halves or units.

The mesh of the metallic structures 17 and 17 is preferably diamond shape as shown in Fig. 5 and extends to the outer or tread surface. It will therefore be seen that a plurality of wire strands will always be presented at theouter or wearing circumference ofthe tread, so asto not only insure greater wearing properties to the tread but to also obtain a more efficient tractive effect.

Having thus disclosed my invention, what I claim as new and desire to secure by Let- Y ters Patent of the United States, is:

1. A protective tread for tires including a laminated structure consisting of a plurality of annular sheets, a metallic wire `structure interposed between the juxtaposed faces of said sheets, a pair of annular rings arranged around the outer side faces of said sheets in outwardly converging relation with respect to each other, and means to clamp said rings and sheets together.

2. A protective tread for tires comprising a laminated structure consisting of a ,plurality of thin annular sheets of semi-resilient material and a metallic wire structure interposed between the juxtaposed faces of said sheets, a pair of annular rings arranged around the outer side faces of said tread and means to'clamp said rings and sheets together, the outer side sheets of said tread being of different widths whereby said rings will be caused to assume an inclined position with respect to said sheets.

3. A protective tread for tires including a plurality of flexiblesheets extending from the rim portion of a tire to form the side portions thereof and the edges of said sheets being arranged to form a. portion of the tread, a plurality of annular sheets arranged in juxtaposed position with the first named sheets and combining therewith to form the tread of the tire, said annular sheets being interposed between certain of said first named sheets, a metallic wire structure interposed between the juxtaposed faces of said flexible sheets, and a pair of rings on opposite sides of the outermost flexible sheets securedk to all of said sheets in outwardly converging relation.`

4. Anl inflatable tire comprising an outer shoe consisting of a plurality of fabric sheets, means interposed between said sheets to form an inner bead portion, said sheets being extended to form the side portions of said tire, and having their outer yedges extended substantially normal to the outer circumference of the main portion of said tire, a plurality of annular sheets of semi-resilient material, between which said outerends arek placed and a metallic wire structure interposed between said annular sheets and said outer` ends of said fabric sheets, said outer ends, annular .sheets and wire structure being pressed together to form a laminated'central unit of a tread, a pair of similar laminated side tread units comprising a plurality of annular ysheets and wire structures arranged in juxtaposed relation and means to clamp said units together.

5. An inflatable tire comprising an outer shoe consisting of a plurality of fabric sheets, means interposed between said sheets to form an inner bead portion, said sheets being extended to form the side portions of 'plurality of annular sheets and wire structures arranged in juxtaposed relation and means to clamp said units together comprising a pair of metal rings at the sides of said side tread units and means to clamp said. rings and units together.

In testimony whereof I have signature.
